We have developed a full suite of tools for analyzing the performance of any materials in cathode applications using the electronic charge density. The new framework required advances in algorithms and data storage strategies that push the boundaries of open-source and open-data materials sciences.
Shortening the excited state lifetime of thermally activated delayed fluorescence in organic light-emitting diodes by conformation distribution management
Given the conformation heterogeneity of thermally activated delayed fluorescence emitters in practical amorphous state in OLEDs, conformation distribution confinement strategy was proposed to develop TADF materials with short excited state lifetime.
A cocrystalline electrolyte for lithium batteries is reported which exhibits an unforeseen best-of-both-worlds combination of liquid and solid electrolytes properties.
A direct observation of up-converted room-temperature phosphorescence in an anti-Kasha dopant-matrix system
It is common sense that emission maxima of phosphorescence spectra (λP) are longer than those of fluorescence spectra (λF). We report a serendipitous finding of up-converted room-temperature phosphorescence with λP < λF and phosphorescence lifetime > 0.1 s in dopant-matrix systems.
We report the use of affordable and widely-available UV-Vis spectroscopy to monitor redox activities during charge storage. The data allowed us to distinguish charge storage mechanisms and quantify the oxidation state changes, similar to synchrotron-based X-ray absorption spectroscopy.
